As you can see from the video above, the iPad 2 using the Apple A5 chip combined with more RAM performs much better than the original iPad when browsing in Mobile Safari. If you load up all nine tabs, you'll see that the original iPad starts to choke up pretty badly when compared to the iPad 2. This is due to the original iPad only coming with 256MB of RAM while iPad 2 comes packed with 512MB. (We hoped for as much as 1GB in the video before getting more test results back. Maybe next year!.)

Earlier today Google rolled out their Instant Previews feature for mobile devices like iPhone. The feature adds elegant thumbnail previews to your search results and works perfectly on your iPhone or iPod touch, even bearing a resemblance to the way Mobile Safari handles tab management.

Instant Previews has been available on the desktop since last year but I never found myself actually using it. I've only been playing with it on my iPhone for a few minutes but can already tell you I'll be using Instant Previews a lot more on the go than I ever did on the desktop. Just tap the little magnifying glass next to your search results to see Instant Previews in action.

If you don't have your iPhone handy then check out the video after the break to get a better idea of how it works, and don't forget to let us know what you think in the comments!

During Apple's iPad 2 announcement yesterday Scott Forstall announced that Mobile Safari was getting a 2x performance boost, in part by porting over Mac OX's Nitro JavaScript engine.

As you surf the web, your fingers will love the responsiveness of the new Nitro JavaScript engine powering Safari. It runs JavaScript up to twice as fast as in iOS 4.2.2 Which means you get more speed behind each page load. And sites with lots of interactive features can appear on your screen even faster.

While AirPrint and AirPlay integration, and Find in Page are the big user-facing features new to iOS 4.2 Safari, MobileXWeb points out that Apple also snuck in a few improvements under the hood:

Accelerometer & Gyroscope support through the DeviceOrientation API

WebSockets API from HTML5

Updated HTML 5 Form Support

Partial XHR-2 Support

New JavaScript data types

New DOM events

Enhanced SVG and Canvas support

If you are a developer let us know how useful these additions will be to your Web Apps. If you're not a developer that might look like mumbo jumbo to you but rest assured it means more better web applications could be coming your way soon, and since Apple uses Safari's WebKit to render everything from iTunes to App Store or iAd to Apple.com, and Google uses it Gmail and pretty much all their sites, there's potential for a lot more, lot better content coming our way.

Google Instant appears to be showing up on the Safari browser for some iPhone, iPod touch, and iPad users. I just checked mine and I've yet to have it roll out here in good old Michigan City (we don't even have 3G yet, so my expectations aren't that high). For those of you not familiar with Google Instant, you search on Google as you normally do but instead of having to hit the search button and wait for the page to come back, results populate as you type.

Google has posted an update to their blogger account notating some new changes to their mobile version of Gmail. From the looks of it, scrolling looks to be much improved as far as smoothness goes. Before the pages seemed to be a bit more choppy and the distance it would scroll wasn't always very accurate. That problem appears to be fixed.

In an effort to slow the already glacial pace of the iOS-friendly HTML5 standard, the WC3 is telling developers to hold off on deploying the technology in their web sites due to lack of interoperability in certain areas.

"The problem we're facing right now is there is already a lot of excitement for HTML5, but it's a little too early to deploy it because we're running into interoperability issues," including differences between video on devices, said the official, Philippe Le Hegaret, W3C interaction domain leader. He is responsible for specifications like HTML and SVG (Scalable Vector Graphics).
